It could be an interesting summer for Sunderland goalkeeper Simon Mignolet. 

His agent has revealed that the Belgian international is unlikely to sign a contract extension at the Stadium of Light. 

Nico Vaesen told the Sunderland Echo that Mignolet has got to a point "where he wants to step up a level", particularly in the lead up to the 2014 World Cup. Belgium has not sealed qualification yet, but if they do, Mignolet faces a battle for the Number 1 spot from Atletico Madrid keeper Thibaut Courtois.

Liverpool and Arsenal are rumoured to be interested in him.
